GeForce 9800 GTX+		145 Watts
	Difference: 40 Watts (38%)

Memory Bandwidth

In theory, the GeForce 9800 GTX+ should perform quite a bit faster than the GeForce 8800 GT 1GB in general. (explain)

GeForce 9800 GTX+		70400 MB/sec
GeForce 8800 GT 1GB		57600 MB/sec
	Difference: 12800 (22%)

Texel Rate

The GeForce 9800 GTX+ is quite a bit (more or less 41%) more effective at anisotropic filtering than the GeForce 8800 GT 1GB. (explain)

GeForce 9800 GTX+		47232 Mtexels/sec
GeForce 8800 GT 1GB		33600 Mtexels/sec
	Difference: 13632 (41%)

Pixel Rate

If running with high levels of AA is important to you, then the GeForce 9800 GTX+ is the winner, by far. (explain)

GeForce 9800 GTX+		11808 Mpixels/sec
GeForce 8800 GT 1GB		9600 Mpixels/sec
	Difference: 2208 (23%)

Please note that the above 'benchmarks' are all just theoretical - the results were calculated based on the card's specifications, and real-world performance may (and probably will) vary at least a bit.

Specifications

Memory Bandwidth: Bandwidth is the maximum amount of data (in units of megabytes per second) that can be transferred past the external memory interface within a second. The number is worked out by multiplying the interface width by its memory speed. In the case of DDR type RAM, it should be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The better the bandwidth is, the better the card will be in general. It especially helps with AA, HDR and higher screen resolutions.

Texel Rate: Texel rate is the maximum number of texture map elements (texels) that can be processed in one second. This number is calculated by multiplying the total amount of texture units by the core speed of the chip. The higher this number, the better the graphics card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied in a second.

Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics chip could possibly record to its local memory per second - measured in millions of pixels per second. The figure is calculated by multiplying the number of colour ROPs by the the core clock speed. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel rate also depends on quite a few other factors, especially the memory bandwidth of the card - the lower the memory bandwidth is, the lower the ability to get to the maximum fill rate.
